Improving the Efficiency and Reliability of Water Systems with Variable Speed Pumps and Pressure Sensors

By Daniel Mullen, Sensata Technologies
Distributing water on a large scale has been a challenge that the world has tackled for decades. It is a particular challenge in high-rise buildings, and with a trend for designers to build up in urban areas, rather than out, it is a challenge that has become a new focus for design engineers.

FCI aims to enhance gas and air ratio control with ST100 flow meter

Installing a direct mass device in the process control loop offers a number of advantages. It allows the operator to achieve a direct ratio of control between the natural gas, the air and waste gas fuels without any corrections for pressure, temperature or density, which requires extra components and possibly extra offsets and failures.

Characteristics of Filling Systems

By Penko
In principle, filling is a dosing process, only much faster. Product that has been produced in one batch, is now filled in multiple packages in succession or simultaneously. The filling process is typically done in a matter of seconds per package, as opposed to minutes or hours.

Proportional valves for closed-loop control of  inert gases in process automation
April 29, 2015

Proportional valves for closed-loop control of inert gases in process automation

By Festo
Proportional valve technology is an interesting alternative for closed-loop control of inert gases in process automation. It achieves the same accuracy as the existing technology, but the level of installation and investment required is lower.

Protect Your Pump & Keep It Longer

By Don Lundberg, FCI
Nothing damages a pump faster than the build-up of heat from dry running conditions. When there’s no liquid to provide cooling, heat destroys a pump’s bearings. This Pump Protection White Paper explains how installing a point flow/level switch in your pump’s process loop can prevent the problem.

Effective Compliance with IEC 61508 When Selecting Solenoid Valves for Safety Systems

Effective Compliance with IEC 61508 When Selecting Solenoid Valves for Safety Systems

Modifications in IEC 61508 regulations mean that industrial automation system designers and users must give new consideration to topics such as SIL levels and the transition from 1H to 2H methodologies. This paper reviews how these issues can impact the choice of solenoid valves and prepackaged redundant control systems (RCS) for implementation in a safety instrumented system (SIS), particularly in the oil, gas, chemical, and power industries. It also explains how making the right choices in planning and valve selection can affect design time, costs, and effort.

Electrical control valve actuators on oil and gas production separators

Electrical control valve actuators on oil and gas production separators

By Rotork
Electric control valve actuators for this type of application require certification for hazardous environments as well as a robust enclosure. They must also have the ability to constantly adjust valve position to accommodate a changing flow rate from the well.

White paper reveals the dangers of carbon residue

By Chris Wright, Global Heat Transfer
When heat transfer fluid (HTF) accumulates carbon residue and coke builds up on internal surfaces, it can lead to fouling, overheating, thermal cracking and choked pipes, creating a fire hazard. Here’s how to maintain thermal fluids and thermal fluid systems.

Asset management in the water industry – the valve actuator’s perspective

By Rotork
In water and effluent treatment environments, the condition of the valves is a fair reflection on the condition of the overall plant, so a great deal of benefit can be gained if the valve actuator can keep the operator informed and updated about the state of the valve that it is operating.

Variable frequency drives: energy savings for pumping applications

By Tom Neuberger and Steven B. Weston, Eaton

Because a VFD alters the frequency of an AC motor, speed, flow, and energy consumption are reduced in the system. The use of VFDs can bring further total system cost reductions, due to the elimination of components required for valve control.

Rupture Pin or rupture disk: which is the clear choice for pressure relief?

Valve World, February 2012

By Julian Taylor, Rupture Pin Technology

The fundamentals of pressure relief applications are safety, efficiency, maintenance level, downtime duration, operating costs and environmental friendliness. Does the Rupture Pin alleviate the issues that go with such applications, or is the rupture disk a more sensible option?
